W/TNESSES UNITED STATES PATENT OFFICE.

WILLIAM H. JONES, OF GLASSBOROUGH, NEW JERSEY, ASSIGNOR TO THE WHITNEYGLASS WORKS, OF SAME PLACE.

GLASS-MOLD.

SPECIFICATION forming part of Letters Patent No. 490,909,.dated January31, 1893.

Application filed April 18, 1892. Serial No. 429,639. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. JONES, a citizen of the United States,residing at Glassborough, county of Gloucester, and State of New Jersey,have invented a new and useful Improvement in Glass-Molds, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention consists of a glass mold pro vided with means,substantially as described,

whereby the same may be readily opened and closed, as will behereinafter fully set forth.

Figure 1 represents a perspective view of a glass mold embodying myinvention. Fig. 2 represents a side view of a portion thereof, theshafts therein being in section. Fig. 3 represents a top view thereofpartly sectional. Fig. 4 represents a horizontal section on line 00, 00,Fig. 2.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings :A designates a table on which is mounted themold B, the same being formed in sections hinged together, so as to beopened and closed.

0 designates a frame which supports said table, and has the horizontalshafts D and E mounted thereon. The shaft D has secured to it at one endthe lever F, and at the other end the arm G.

Loosely mounted on the shaft D adjacent to the arm G, is a lever H, theupper end whereof carries a pivotal link or hook J, the latter engagingwith the handle K of one of the sections of the mold, said lever alsoabutting against said handle, as most plainly shown in Fig. 2.

The upper end of the lever F, carriesa pivotal link or hook L, whichengages with the handle M of the other section of the mold, said lever Falso abutting against said handle, all as will be seen most plainly inFig. 3.

Projecting from the lever H, is a pin N, which is adapted to be engagedby the arm G, so as to impart motion to said lever in one direction.

To the shaft D, is screwed or otherwise secured the crank-wheel P, tothe periphery of which is attached a strap Q, the lower end whereof isconnected with a foot treadle R, whereby rotation may be imparted tosaid shaft D, but to this mechanism for rotating .thereof is secured tothe shaft E, the latter also carrying an arm T, which is pivoted to thestem U of a follower or foot piece V, said stem being vertically movablein a suitable guide W on the frame A.

Connected with'the lever F, and a proper part of the frame 0, is aspring X, for returning said lever and connected section of the mold totheir normal positions.

The operation is as followsz-An attendant depresses the treadle R,whereby the shaftD is rotated, and motion is imparted to the lever F, insuch manner that the connected mold section is opened. The arm G on theshaft D also strikes the pin N, whereby the arm H is moved so as to openthe mold section connected with the same. The treadle is let go, whenthe spring X causes the return of the lever F, and consequent closing ofthe mold section attached thereto, and the glass is now placed in saidsection. Another workman now depresses the follower V,whereby, owing tothe operation of the arm T, shaft E, and toggle lever S, the other moldsection is closed, the metal or glass then beingblown, the effect ofwhich is evident. When the treadle is again depressed, the operation ofopening the mold is repeated,when the molded glass may be removed, freshmetal supplied to the mold, and the sections again closed, and so theoperations may be continued.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is:-

1. A glass mold formed in hinged sections,

engage with said loose lever, whereby both sections of the mold may besimultaneously opened when the shaft is rotated, the parts named beingcombined substantially as described.

3. A glass mold having leversconnected with the sections thereof, arotary shaft having one of said levers fixed thereto, and the otherlever loosely mounted thereon, a spring attached to the fixed shaft, atoggle lever connected with the loosely mounted lever, a shaft fixed1ever,a toggle lever pivoted to freely mounted lever, a rotary shaft towhich the latter is pivoted, and means to operate said shafts, theseveral parts being combined substantially as described, whereby themold may be opened and closed as stated.

5. A frame with a table thereon, a hinged sectional mold supported onsaid table, two shafts mounted in said frame, levers on one of saidshafts and connected with sections of the mold for opening the same, aspring connected with one of the levers for closing its section, and alever mounted on the other shaft and connected with the other lever ofthe first shaft for closing its section, said parts being combinedsubstantially as described.
